DeTar, Carleton | B→πlν semileptonic form factor from three-flavor lattice QCD: a model-independent determination of [Vub] | We calculate the form factor f+(q2) for B-meson semileptonic decay in unquenched lattice QCD with 2 + 1 flavors of light sea quarks. We use Asqtad-improved staggered light quarks and a Fermilab bottom quark on gauge configurations generated by the MILC Collaboration. We simulate with several light... | Semileptonic decay | 2009-03 |

Vardeny, Zeev Valentine; Nahata, Ajay | Terahertz spectroscopy of plasmonic fractals | We use terahertz time-domain spectroscopy to study the transmission properties of metallic films perforated with aperture arrays having deterministic or stochastic fractal morphologies (‘‘plasmonic fractals''), and compare them with random aperture arrays. All of the measured plasmonic fractals... | Plasmonic fractals; Random aperture arrays | 2009-03 |
